Primary Epithelioid Hemangioendothelioma of the Kidney: The First Case Report in a Child and Literature Review

Pediatric Anastomosing Hemangioma: Case Report and Review of Renal Vascular Tumors in Children

“…5 There have been only 2 other reported pediatric cases with renal anastomosing hemangiomas, teenagers who had small lesions and coexisting kidney diseases. 19 The present patient had a massive lesion yet the nonneoplastic renal parenchyma was otherwise normal. The other older patients listed in Table 1 presented with hematuria and were diagnosed as having renal cavernous hemangiomas.…”

“…A summary of the 50-year literature of pediatric renal vascular tumor cases (exclusive of malformations) is provided in Table 1. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] The list includes recent histologic diagnoses which are either provisionally or not yet incorporated in the International Society for the Study of Vascular Anomalies (ISSVA) classification system. 23 One of the uncategorized lesions is anastomosing hemangioma, which was recently described and has since been increasingly reported in the literature.…”

A Case Report of Prostatic and Peritoneal Hemangioendothelioma

“…When discovered in the bladder, the common presenting complaint is hematuria (4). When involving the kidney, it can be discovered on imaging as a heterogeneous mass (6). In our patient, imaging suggested the possibility of a prostatic abscess.…”

Vascular Neoplasms and Related Lesions of Kidney

“…Epithelioid hemangioendothelioma (EHE) is a vascular tumor with generally intermediate biologic behavior but notably harboring the potential to metastasize [40]. While EHE can occur at a variety of locations (most commonly soft tissue, lung, and liver), primary EHE arising from the kidney is exceedingly rare with only five cases reported in the literature to date [41][42][43][44][45]. The median age of occurrence is 53 years and no particular sex predilection has been observed.…”

“…Singlecase studies have demonstrated hypoechogenicity on ultrasound examination and solid lesions lacking significant enhancement on CT imaging [43,45]. On MRI, Xiao et al reported heterogeneous intensity on T1-weighted images with diminished intensity on T2weighted images and heterogeneous, persistent enhancement with contrast administration [44]. Overall, the clinical and radiologic findings are nonspecific and preclude definitive pre-operative diagnosis.…”
